"As a parent it made me question why I taught her to be so polite in that moment."

Taylor Swift's trial against former Denver radio DJ David Mueller began in Colorado this week. The singer-songwriter is countersuing Mueller, whom she alleges groped her at a pre-concert meet and greet in 2013 — a claim that Mueller has vehemently denied. While Taylor has yet to take the stand, her mother, Andrea, gave an emotional testimony on Wednesday, sharing everything she knew about her daughter's fateful evening.

"I knew what happened, I heard it from her, I heard it from my daughter's mouth. He sexually assaulted her, right there, that guy," the singer's mother said in court, pointing at Mueller, according to E! News. Breaking down in tears numerous times during her testimony, Swift's mother also said that Taylor told her: "Mom, a guy just grabbed my ass in the meet and greet."

"She couldn't believe that after he grabbed her, that she thanked them for being there," Andrea Swift continued. "It was just destroying her that she said that . . . as a parent it made me question why I taught her to be so polite in that moment." Additionally, Taylor's mother explained that when talking over what had transpired, the two decided not to alert the police at the time, in fear it would "define" Taylor's life in the coming years.

"I did not want her to have to live through the endless memes and GIFs and anything else that tabloid media or trolls would be able to come up with . . . making her relive this awful moment over and over again," Swift's mother said. "I was upset to the point where I wanted to vomit and cry at the same time."

Mueller is currently suing Taylor for slander because of the groping allegations, claiming that they ruined his career. In turn, Taylor countered with a battery and sexual assault suit, arguing that it will "serve as an example to other women who may resist publicly reliving similar outrageous and humiliating acts." While Mueller is asking for $3 million in damages, Taylor is asking for only $1.
